Joshua Harvey: The evolution of the human eye (2015x3)

: 08, 2015

The human eye is an amazing mechanism, able to detect anywhere from a few photons to a few quadrillion, or switch focus from the screen in front of you to the distant horizon in a third of a second. How did these complex structures evolve? Joshua Harvey details the 500 million year story of the human eye. [Directed by Artrake Studio, narrated Addison Anderson, music by Bojana Vunturišević].
